RELATED APPLICATIONS

This application is a divisional of copending U.S. patent application Ser. No. 12/547,246, filed Oct. 25, 2009; which is herein incorporated by reference.

BACKGROUND

The present invention relates to thin film processing, and more particularly, this invention relates to methods for fabricating magnetic writer structures using post-deposition tilting.

In magnetic storage systems, data is read from and written onto magnetic recording media utilizing magnetic transducers commonly. Data is written on the magnetic recording media by moving a magnetic recording transducer to a position over the media where the data is to be stored. The magnetic recording transducer then generates a magnetic field, which encodes the data into the magnetic media. Data is read from the media by similarly positioning the magnetic read transducer and then sensing the magnetic field of the magnetic media. Read and write operations may be independently synchronized with the movement of the media to ensure that the data can be read from and written to the desired location on the media.

An important and continuing goal in the data storage industry is that of increasing the density of data stored on a medium. For magnetic storage systems, that goal has lead to increasing the linear density and track density on recording tape or hard disk, and in some cases decreasing the thickness of the magnetic medium. However, the development of small footprint, higher performance magnetic storage systems has created various problems in the design of a head assemblies for use in such systems.

A method according to another embodiment includes forming a first portion of a thin film writer structure on a substantially planar portion of a substrate such that planes of deposition of the first portion of the writer structure is substantially parallel to a plane of the substrate; forming a sloped portion towards one side of the first portion of the writer structure, an upper surface of the sloped portion having an angle of greater than 0° relative to the substantially planar portion of the substrate; forming a portion of a first pole of the writer structure on the sloped portion; forming a write gap on the portion of the first pole; forming a portion of a second pole of the writer structure on the write gap; causing the writer structure to tilt at an angle relative to the plane of the substrate such that a plane of deposition of the write gap is about perpendicular to a final media-facing surface of the writer structure; and after causing the writer structure to tilt, fixing the writer structure in place on the substrate at the angle.

Any of these embodiments may be implemented in a magnetic data storage system such as a tape drive system, which may include a magnetic head as recited above, a drive mechanism for passing a magnetic medium (e.g., recording tape) over the magnetic head, and a controller electrically coupled to the magnetic head.

FIG. 1 illustrates a simplified tape drive 100 of a tape-based data storage system, which may be employed in the context of the present invention. While one specific implementation of a tape drive is shown in FIG. 1, it should be noted that the embodiments described herein may be implemented in the context of any type of magnetic recording system.

As shown, a tape supply cartridge 120 and a take-up reel 121 are provided to support a tape 122. One or more of the reels may form part of a removable cassette and are not necessarily part of the system 100. The tape drive, such as that illustrated in FIG. 1, may further include drive motor(s) to drive the tape supply cartridge 120 and the take-up reel 121 to move the tape 122 over a tape head 126 of any type.

Guides 125 guide the tape 122 across the tape head 126. Such tape head 126 is in turn coupled to a controller assembly 128 via a cable 130. The controller 128 typically controls head functions such as servo following, writing, reading, etc. The cable 130 may include read/write circuits to transmit data to the head 126 to be recorded on the tape 122 and to receive data read by the head 126 from the tape 122.

An interface may also be provided for communication between the tape drive and a host (integral or external) to send and receive the data and for controlling the operation of the tape drive and communicating the status of the tape drive to the host, all as will be understood by those of skill in the art.

By way of example, FIG. 2 illustrates a side view of a bi-directional, two-module magnetic tape head 200 which may be implemented in the context of the present invention. As shown, the head includes a pair of bases 202, each equipped with a module 204, and fixed at a small angle α with respect to each other. The bases are typically “U-beams” that are adhesively coupled together. Each module 204 includes a substrate 204A and a closure 204B with readers and/or writers formed thereon. In use, a tape 208 is moved over the modules 204 along a media (tape) bearing surface 209 in the manner shown for reading and writing data on the tape 208 using the readers and writers. The wrap angle θ of the tape 208 at edges going onto and exiting the flat media support surfaces 209 are usually between ⅛ degree and 4½ degrees.

The substrates 204A are typically constructed of a wear resistant material, such as AlTiC, a ceramic, etc.

The readers and writers may be arranged in a piggyback configuration. The readers and writers may also be arranged in an interleaved configuration. Alternatively, each array of channels may be readers or writers only. Any of these arrays may contain one or more servo readers.

FIG. 3 illustrates a method according to one embodiment. As an option, the present method 300 may be implemented in the context of the functionality and architecture of FIGS. 1-2 and 5-8. Of course, the method 300 may be carried out in any desired environment. It should be noted that the aforementioned definitions may apply during the present description.

With continued reference to FIG. 3, in operation 302, a first portion of a thin film writer structure is formed on a substantially planar portion of a substrate such that planes of deposition of the first portion of the writer structure is substantially parallel to a plane of the substrate. In FIG. 5A, for example, the first portion that is formed on a substrate is the coil 502 and lower yoke 504, along with an insulator 506. However, this example does not in any way limit what may be the first portion of the writer structure 500 that is formed.

With continued reference to FIG. 3, in operation 304, a portion of a write gap of the writer structure is formed at an angle of greater than 0° relative to the substantially planar portion of the substrate. In FIG. 5C, for example, this portion of at least one pole of the writer structure is shown as a ramp 510 formed toward the write side 508 of the writer structure 500. This example in no way limits the design and appearance of this ramp.

In operation 306, the writer structure is caused to tilt at an angle relative to the plane of the substrate such that a plane of deposition of the write gap is oriented about perpendicular to a final media-facing surface of the writer structure. Note that the “final media-facing surface” is meant to mean the surface that faces the media in the final product as sold. For example, the final media-facing surface may be an air bearing surface (ABS), tape bearing surface (TBS), etc. in a magnetic storage device. In many embodiments, the media-facing surface will be about parallel to the plane of the substrate. In FIG. 5H, for example, the writer structure 500 is tilted at an angle θ relative to the planar surface of the substrate. This example is not limiting as to the angle and direction in which the writer structure 500 may be tilted.

In optional operation 308, after causing the writer structure to tilt, the writer structure may be fixed in place on the substrate at the angle. In FIG. 5I, for example, the writer structure 500 may be fixed in place with a material 522, which is then planarized as shown in FIG. 5J. This example is not limiting as to the type of material that is used to fix the writer structure 500 in place. In some approaches, operation 308 may be omitted.

In further approaches, the writer structure may be self-fixing, e.g., by a pre-applied adhesion layer, by naturally-occurring attractive forces with an underlying layer, etc.

In yet other approaches, a protective layer may be added to the writer structure, which may have the effect of fixing the writer structure in place.

In one embodiment, the substrate comprises silicon.

In another embodiment, the writer structure may be planarized along a plane substantially parallel to the plane of the substrate.

In yet another embodiment, the writer structure may be formed on a rigid platform that tilts with the writer structure.

In a further embodiment, an axis of the tilting is about parallel to the plane of the substrate.

Yet another approach includes portions of two poles that may be formed at an angle of greater than 0° relative to the substantially planar portion of the substrate.

Another embodiment further comprises forming a magnetic sensor, wherein the sensor and the writer structure tilt together, as shown in FIGS. 8A and 8B.

Yet another embodiment further comprises removing a sacrificial portion of the substrate for creating a pivot point about which the writer structure may pivot, allowing the writer structure to be tilted relative to the plane of the substrate. Another embodiment which uses a pivot point may include the pivot point under and off-center from the writer structure.

A further embodiment which includes a pivot point wherein removing a portion of the substrate allows built-in stresses to cause the writer structure to tilt at the desired angle.

Yet another approach which includes a pivot point may have the pivot point spaced apart from the writer structure such that the writer structure pivots along an arc. Also, another approach may use capillary action operatively to cause the writer structure to tilt at the desired angle. Another embodiment may include removing a sacrificial portion of the substrate to cause another portion of the substrate to form a cantilever supporting the writer structure, wherein a local stress operatively causes the cantilever to bend, thereby causing the writer structure to tilt at the desired angle.

FIG. 4 illustrates a method according to one embodiment. As an option, the present method 400 may be implemented in the context of the functionality and architecture of FIGS. 1-2 and 5-8. Of course, the method 400 may be carried out in any desired environment. It should be noted that the aforementioned definitions may apply during the present description.

With continued reference to FIG. 4, in operation 402, a first portion of a thin film writer structure is formed on a substantially planar portion of a substrate such that planes of deposition of the first portion of the writer structure is substantially parallel to a plane of the substrate.

In operation 404, a sloped portion is formed towards one side of the first portion of the writer structure, an upper surface of the sloped portion having an angle of greater than 0° relative to the substantially planar portion of the substrate.

In operation 406, a portion of a first pole of the writer structure is formed on the sloped portion.

In operation 408, a write gap is formed on the portion of the first pole.

In operation 410, a portion of a second pole of the writer structure is formed on the write gap.

In operation 412, the writer structure is caused to tilt at an angle relative to the plane of the substrate such that a plane of deposition of the write gap is about perpendicular to a media-facing surface of the writer structure.

In operation 414, after causing the writer structure to tilt, the writer structure is fixed in place on the substrate at the angle.

In another embodiment, the writer structure may be planarized along a plane substantially parallel to the plane of the substrate. Illustrative planarization techniques include chemical-mechanical polishing (CMP), grinding, etc.

In FIG. 5C, a subsequent step in a process to produce a tilted writer structure 500 is shown according to one embodiment. In this figure, a ramp 510 is formed on the side (as indicated by arrow 508) of the writer structure 500. This ramp 510 may be made of any suitable material including insulating or magnetic materials. The ramp 510 will be used in the next few processing steps to further produce the tilted writer structure 500.

In FIG. 5D, a subsequent step in a process to produce a tilted writer structure 500 is shown according to one embodiment. In this figure, a first pole (P1) 512 is formed on the ramp 510 and on the back side of the writer structure 500.

In FIG. 5F, a subsequent step in a process to produce a tilted writer structure 500 is shown according to one embodiment. In this figure, a write gap 516 is formed on top of the first pole 512 and insulator layer 514. This next insulator layer 514 may be of the same material as the first insulator layer 506, or may be of a differing material selected for its insulative properties.

In FIG. 5G, a subsequent step in a process to produce a tilted writer structure 500 is shown according to one embodiment. In this figure, a second pole (P2) 518 is formed on the write gap 516. A fill layer 519 may be added over the second pole.

In FIG. 5H, a subsequent step in a process to produce a tilted writer structure 500 is shown according to one embodiment. In this exemplary figure, the writer structure 500 is tilted at an angle θ relative to the planar surface of the substrate. In some approaches, the writer structure 500 may be tilted by pivoting a supporting layer 521 about a pivot point. The pivot point may be positioned at a point along the length of layer 521. Other methods of tilting may also be employed, as described elsewhere herein.

For simplicity, the optional fill layer 519 and supporting layer 521 are not shown in the following figures. In FIG. 5I, a subsequent and optional step in a process to produce a tilted writer structure 500 is shown according to one embodiment. In this figure, a material 522 is formed around the writer structure 500. This material may be used to fix or protect the writer structure. The material is capable of holding the writer structure in place or protecting it, and does not interfere with the operation of the writer structure 500.

In FIG. 5J, a subsequent step in a process to produce a tilted writer structure 500 is shown according to one embodiment. In this figure, the writer structure 500 and fixing material 522 is planarized (as indicated by the dashed line) to form the recording surface. Further processing may occur, or the writer structure 500 may be ready for writing operations.

A write gap 614 is positioned between the poles 610, 612, a portion of the write gap having a plane of deposition oriented about perpendicular to a final media-facing surface 604 of the write gap. For example, the final media-facing surface may be an air bearing surface (ABS), tape bearing surface (TBS), etc. In many embodiments, the media-facing surface will be about parallel to the plane of the substrate.

In one particularly preferred embodiment, the portion of the writer structure 600 which is in contact with the media surface 604 is perpendicular to the media surface 604. This arrangement creates a highly symmetric magnetic field when a writing operation is performed.

In another embodiment, the writer structure 600 is further comprised of a sloped portion under the first pole 610, the sloped portion having an upper surface oriented about perpendicular to a media-facing surface of the at least one pole. Such a sloped portion may be similar to the ramp described with reference to FIG. 5C.

In this diagram, etching, e.g., isotropic etching, is used to form the ramp 712 which becomes a portion of the first pole 702. Also a portion of the pole material 714 may be formed in this step and will become a portion of the back gap in a subsequent step.

FIG. 7D is a schematic diagram of a subsequent step in the production of a writer structure 700 according to one embodiment. In this diagram, a write gap 716 is formed above the top of the ramp and coil structure. Then, a pole material is formed above the write gap 716 and connecting to the back gap 718 portion of the first pole 702. This pole material forms the top pole (second pole) 720. This writer structure can then be tilted at an angle of between about 0° and less than 90°.
